SUPPLEMENTARY INFORMATION:

Background

On February 26, 2026, Commerce published the Preliminary Determination and invited interested parties to comment.^[1] In accordance with section 705(a)(1) of the Tariff Act of 1930, as amended (the Act), and 19 CFR 351.210(b)(4), Commerce aligned the deadline for this countervailing duty (CVD) final determination with the deadline for the final determination in the companion less-than-fair-value investigation of solar cells from India.^[2]

For a complete description of the events that occurred since the Preliminary Determination, as well as a full discussion of the issues raised by parties for this final determination, see the Issues and Decision Memorandum.^[3] The Issues and Decision Memorandum is a public document and is on file electronically via Enforcement and Compliance's Antidumping and Countervailing Duty Centralized Electronic Service System (ACCESS), which is available to registered users at access.trade.gov. In addition, a complete version of the Issues and Decision Memorandum can be accessed directly at access.trade.gov/​frnotices.

Scope of the Investigation

The product covered by this investigation is solar cells from India. For a complete description of the scope of this investigation, see Appendix I.

Scope Comments

In the Preliminary Scope Memorandum, we set aside a period of time for parties to raise issues regarding product coverage ( i.e., scope) in scope-specific case briefs or other written comments.^[4] We received scope case and rebuttal briefs from multiple interested parties. For a summary of the product coverage comments and rebuttal responses submitted to the record for this final determination, and accompanying discussion and analysis of all comments timely received, see the Final Scope Memorandum.^[5] In the Final Scope Memorandum, Commerce determined that it is not modifying the scope language as it appeared in the Initiation Notice.⁶ See Appendix I.

Final Affirmative Determination of Critical Circumstances, in Part

In the Preliminary Determination, in accordance with section 703(e)(1) of the Act, Commerce found that critical circumstances exist with respect to imports of solar cells from India for Mundra Solar Energy and Mundra Solar PV, but do not exist with respect to all other producers and/or exporters not individually examined. In this final ( printed page 58644) determination, Commerce continues to find that critical circumstances exist for Mundra Solar Energy and Mundra Solar PV, and that critical circumstances do not exist for all other producers and/or exporters of solar cells from India, pursuant to section 705(a)(2) of the Act and 19 CFR 351.206. For a discussion of Commerce's critical circumstances analysis, see the Issues and Decision Memorandum.

Verification

Because the mandatory respondents, Mundra Solar Energy Ltd. (Mundra Solar Energy) and Mundra Solar PV Limited (Mundra Solar PV), did not participate in this investigation, Commerce did not conduct verification.

Analysis of Subsidy Programs and Comments Received

The subsidy programs under investigation, and the issues raised in the case and rebuttal briefs that were submitted by parties in this investigation, are discussed in the Issues and Decision Memorandum. For a list of the issues raised by parties, and to which we responded in the Issues and Decision Memorandum, see Appendix II.

Methodology

Commerce conducted this investigation in accordance with section 701 of the Act. For each of the subsidy programs found to be countervailable, Commerce determines that there is a subsidy, i.e., a financial contribution by an “authority” that gives rise to a benefit to the recipient, and that the subsidy is specific.^[7] For a full description of the methodology underlying our final determination, see the Issues and Decision Memorandum. In making this final determination, Commerce relied on facts otherwise available, including with an adverse inference (AFA), pursuant to sections 776(a) and (b) of the Act. For a full discussion of our application of AFA, see “Use of Facts Otherwise Available and Application of Adverse Inferences” section in the Issues and Decision Memorandum.

Changes Since the Preliminary Determination

Based on our review of comments received from parties, for this final determination, we made certain changes to the selection of the rates for Mundra Solar Energy and Mundra Solar PV and all other producers/exporters. For a discussion of these changes, see the Issues and Decision Memorandum.

All-Others Rate

Sections 703(d) and 705(c)(5)(A) of the Act provide that Commerce shall determine an estimated all-others rate for companies not individually examined. This rate shall be an amount equal to the weighted average of the estimated subsidy rates established for those companies individually examined, excluding any zero and de minimis rates and any rates based entirely under section 776 of the Act.

Pursuant to section 705(c)(5)(A)(ii) of the Act, if the individual estimated countervailable subsidy rates established for all exporters and producers individually examined are zero, de minimis, or determined entirely under section 776 of the Act, Commerce may use any reasonable method to establish the estimated subsidy rate for all other producers and/or exporters.

In this investigation, Commerce has determined the subsidy rate for the individually examined respondents under section 776 of the Act. This is the only rate available in this proceeding for deriving the all-others rate. Consequently, as a reasonable method, pursuant to sections 703(d) and 705(c)(5)(A)(ii) of the Act, Commerce established the all-others rate by applying the countervailable subsidy rate assigned to Mundra Solar Energy and Mundra Solar PV, the mandatory respondents in this investigation, as determined under section 776 of the Act.^[8] For a full description of the methodology underlying Commerce's analysis, see the Issues and Decision Memorandum.

Final Determination

Commerce determines that the following estimated countervailable subsidy rates exist for the period, April 1, 2024, through March 31, 2025:

Disclosure

Commerce normally discloses the calculations and analysis performed to interested parties in this final determination within five days of any public announcement or, if there is no public announcement, within five days of the date of publication of the notice of final determination in the Federal Register , in accordance with 19 CFR 351.224(b). However, because Commerce applied AFA to the mandatory respondents, in accordance with section 776 of the Act, there are no calculations to disclose for this final determination.

Continuation of Suspension of Liquidation

As a result of our Preliminary Determination and pursuant to sections 703(d)(1)(B) and (d)(2) of the Act, we instructed U.S. Customs and Border Protection (CBP) to collect cash deposits and suspend liquidation of entries of subject merchandise produced and/or exported by all other producers and/or exporters that were entered, or withdrawn from warehouse, for consumption on or after February 26, 2026, the date of the publication of the Preliminary Determination in the Federal Register .^[9] Additionally, in accordance with section 703(e)(2)(A) of the Act, because we preliminarily determined that critical circumstances existed, we instructed CBP to suspend liquidation of entries of subject merchandise produced and/or exported by Mundra Solar Energy and Mundra Solar PV that were entered, or withdrawn from warehouse for consumption on or after November 28, 2025, which is 90 days before date of the publication of the Preliminary Determination in the Federal Register .^[10] In accordance with section 703(d) of the Act, we instructed CBP to discontinue the suspension of liquidation of all entries of subject merchandise entered or withdrawn from warehouse, on or after June 26, 2026, the first day provisional measures were no longer in effect, but to continue the suspension of liquidation of all entries of subject merchandise on or before June 25, 2026.

If the U.S. International Trade Commission (ITC) issues a final affirmative injury determination, we will issue a CVD order, reinstate the suspension of liquidation under section 706(a) of the Act, and require a cash deposit of estimated countervailing duties for entries of subject merchandise in the amounts indicated above. Pursuant to section 705(c)(2) of the Act, ( printed page 58645) if the ITC determines that material injury, or threat of material injury, does not exist, this proceeding will be terminated, and all estimated duties deposited or securities posted as a result of the suspension of liquidation will be refunded or canceled.

ITC Notification

In accordance with section 705(d) of the Act, Commerce will notify the ITC of its final affirmative determination that countervailable subsidies are being provided to producers and/or exporters of solar cells from India. Because the final determination is affirmative, in accordance with section 705(b) of the Act, the ITC will determine, within 45 days, whether the domestic industry in the United States is materially injured, or threatened with material injury, by reason of imports of solar cells from India. In addition, we are making available to the ITC all non-privileged and non-proprietary information related to this investigation. We will allow the ITC access to all privileged and business proprietary information in our files, provided the ITC confirms that it will not disclose such information, either publicly or under an administrative protective order (APO), without the written consent of the Assistant Secretary for Enforcement and Compliance.

If the ITC determines that material injury or threat of material injury does not exist, this proceeding will be terminated, and all cash deposits will be refunded. If the ITC determines that such injury does exist, Commerce will issue a CVD order directing CBP to assess, upon further instruction by Commerce, countervailing duties on all imports of the subject merchandise that are entered, or withdrawn from warehouse, for consumption on or after the effective date of the suspension of liquidation, as discussed above in the “Continuation of Suspension of Liquidation” section.

Administrative Protective Order

In the event that ITC issues a final negative injury determination, this notice will serve as the only reminder to parties subject to an APO of their responsibility concerning the destruction of proprietary information disclosed under APO, in accordance with 19 CFR 351.305(a)(3). Timely written notification of the return/destruction of APO materials or conversion to judicial protective order is hereby requested. Failure to comply with the regulations and terms of an APO is violation which is subject to sanction.

Notification to Interested Parties

This determination is issued and published pursuant to sections 705(d) and 777(i)(1) of the Act, and 19 CFR 351.205(c).
